Are roundoff errors on the order of one part in 2^56 really a deal-breaker for your application?
I mean, “17.300000000000000711” does _look_ ugly compared to “17.3”, but the difference
is completely negligible for most purposes. Have you worked out how many significant figures
of accuracy you need, and are the results correct to within those significant figures?
